Mylohyoid Muscle Floor Of Mouth
Over time this muscle may begin to weaken which may.
Mylohyoid muscle floor of mouth. Geniohyoid muscle musculus geniohyoideus geniohyoid muscle is a short paired muscle that belongs to the suprahyoid muscle group of the neck together with the digastric stylohyoid and mylohyoid muscles it constitutes the floor of the oral cavity. The mylohyoid muscle functions to depress the jawbone elevate the hyoid bone and raise the floor of the mouth. Together the paired mylohyoid muscles form a muscular floor for the oral cavity of the mouth. The muscle pair attaches to a ridge on the inner surface of the lower jawbone called the mylohyoid line.
Geniohyoid muscles where is the insertion and origin of the geniohyoid muscles. More posteriorly between the mylohyoid and the tongue lies the hyoglossus muscle which in fact is the side wall of the tongue. Forming the floor of the mouth the superior surface of mylohyoid muscle is related to the structures of the oral cavity. If the mylohyoid muscle is refletcted what muscle can be seen in the floor of mouth.
The mylohyoideus mylohyoid muscle flat and triangular is situated immediately above the anterior belly of the digastricus and forms with its fellow of the opposite side a muscular floor for the cavity of the mouth it arises from the whole length of the mylohyoid line of the mandible extending from the symphysis in front to the last molar tooth behind. It is a pharyngeal muscle derived from the first pharyngeal arch and classified as one of the suprahyoid muscles. It depresses the mandible raises the floor of the mouth during the beginning of deglutition swallowing and it elevates the hyoid. Above the mylohyoid is the mouth and below is the neck.
Mylohyoid muscle in situ. The mylohyoid muscle works to perform three separate functions. The mylohyoid muscle is actually a pair of muscles that form part of the floor of the mouth as highlighted in physiopedia. It lies directly beneath the geniohyoid hyoglossus and styloglossus muscles hypoglossal cn xii and lingual nerves submandibular ganglion sublingual and submandibular glands and the lingual artery and.
Its main function is to coordinate the movements of the floor of the mouth and the hyoid bone while swallowing and voice production. The squamous epithelium at the mucosal surface and other superficial anatomic components of the floor of the mouth are easily evaluated at physical examination the mylohyoid muscle sling is formed by the paired mylohyoid muscles which arise from the inner surface of the mandible extend from the symphysis anteriorly to the last molar tooth posteriorly and insert onto the posterior aspect. The mylohyoids are reinforced superiorly by the two geniohyoids. The mylohyoid is a flat triangular shaped muscle that begins at the jawbone and extends to the hyoid bone between the neck and chin.
